Do you know what the profile height is? 235/??/R15? That makes all the difference. I assume they're mud terrains or all terrains in which case they're probably 235/75/R15, that being the case the fronts will most probably rub the bumper, springs & anti-roll bar when turning the steering, and up under the wheelarches when flexing. You could fit spacers (I hate spacers by the way ), I think the most common ones are about 25 - 30 mm, but then you'd still need to remove or trim the bumper and she'd still rub under the arches when flexed....

I've personally got 215/80/R15s on standard rims, they're a little narrower but about the same height as 235/75s. I've done a 2" body lift for clearance under the arches, then re-mounted the front bumper 2" higher and about an inch further forward, oh and I don't have an anti-roll bar any more. They occasionally catch the springs on full lock, but not always and never enough to worry about.... No other problems at all _________________
